CORPORATIONOF GERMANY BAnnAen Application. vfiled November 18, 1926. Serial No.149,9391.

This invention relates to improvements in bandages, particularly'thoseapplicable for use in treating sprains, strains or other body injuriesrequiring a firm retention of the injured member in a positive position.

As is known at the present time, injuries such as broken bones orsprains require the use of splints or plaster casts for the retention'ofthe injured member inits rigid position for proper healing. Of course,bandages comprislng the ordinary adhesive or non-adhesive gauze arewound over the splints to maintain the splints in proper position foracting correctly upon the injured member.

It is for the purpose of eliminating the useof these reinforcing memberssuch as splints or plaster casts, and at the same time for bringingabout a more simple and facile manner of treating such injuries that theapplicant has devised a plaster comprising an elastic porous wovenbandage having formed on one surface thereof a coating of adhesive I andat the same time healing properties.

Generally, it is the aim of this invention to provide for a bandage forthe above specified purposes, which bandage due to its elasticity orflexibility may be wound about the injured body member and upon beingdrawn taut will, due to its adhesive properties, bring about a positivereinforcement and protection with respect to the injured member.

Further, it is an object of this invention to so provide this elasticbandage so as to introduce the feature of porosity therein, whereby theinjured member may not be completely segregated or separated from aircontact. Of course the adhesive remedial which comprises the well knownrubber or gum member impregnated with a medicinal preparation will moreor less form an air-tight coating on one face of the bandage, that is,thc face which is in direct contact with the injured body member, butthe property of flexibility and elasticity inherent in this bandage willcause the formation of air spaces or passages therein capable ofallowing the passage therethrough of air.

Generally, among the objects of the invention it is aimed to provide anovel form of bandage containing adhesiveand medlcinal ingredientswhereby a positive rigidity may;

be imparted to the injured member about which this bandage is wound; toprovide a novel form of bandage comprising a warp and woof so wound withrespect to one another as to provide a longitudinal flexibility wherebythe application of the bandage with its adhesive coating under tensionto the injured member will bring about an immovable and practicallyrigid positioning of the injured body member; to provide a novel form ofbandage having adhesive medicinal preparation thereon, which combinesthe property of a covering for the injured memher and at the same timeimparts thereto the rigidity formerly provided by splints, plaster castsand other independent extraneous members with which the bandage wasusually associated; thus the elimination of a splint or plaster castbetween inner and outer bandages ghereby to form a reinforcing mediumthere- .These and other advantages, capabilities, and features of theinvention will appear from the subjoined detail description of onespecific embodiment therefor illustrated in the accompanying drawings,in which Fig. 1 is an isometric view of the bandage element.

Fig. 2 is a bottom view looking upwards of Fig. 1 of the bandage in itsnormal position.

.Fig. 3 is a bottom view looking upwards of Fig. 1 of the bandage inextended or stretched condition.

Referring to Fig. 1, numeral 4 represents the bandage element of whichthe base portion 5 represents a woven member.and the upper portion 6represents a layer of adhesive material placed thereon by variousmethods of which spraying or coating is typically representative of oneof the methods of applying the same to the woven base.

As shown in Fig. 3, the base member 5 comprises a woven member having aheavy Weft woof threads, as shown in Figs. 2 and 3,so that there isconsiderable stretch in the warp with respectto the woof.

Since this bandage is formed by this particular method of weaving,wherein the heavy weft or woof 7 is crossed in alternate position bymuch finer warp members, a considerable-porosity is introduced withinthe woven member, especially when the woven member is stretched upon theapplication of the bandage with the adhesive member 6 at one surfacethereof.

When a broken body member is to be bandaged the operator merely takes alength of this bandage with the adhesive element on one face thereofandwinds the same under tension about the injured member; since thebandage has considerable elasticity due to the formation of the wovenbase and since the adh sive member in its nature is elastic, the bandageupon being applied about the in jured member in a taut manner obviouslythe use of splints or other fixed supporting mem bers usually associatedwith bandages is eliminated. In actual ap lication the applicant hastaken a length of" the same under tension about an injured, particularlyabroken member, and due to the firmness of the bandage and after it hadbeen stretched irito position, the usual splints or plaster casts havebeen eliminated and the same results that are usually obtained with pthe above are produced with a minimumof effort and a considerableeconomy of cost and time.

* Further, the bandage being of adhesive type remains fined and cannotmove, due to the adhesive member associated therewith and due to thefact that it has been stretched due to its elasticity so that thebandage will never be loose and will always introduce a firm constantpressure of undiminished quantum. t

To clearly illustrate the function of this particular bandage Figs. 2and 3 have been drawn to illustrate the comparative porosity andelasticity of the member. It should be noted that. in Fig. 2 the warpmembers 8 are quite close to one another and to the. woof member 7whereas in Fig. 3 when the bandandage and wound It is obvious thatvarious changes and modifications may be made to the details ofconstruction without departing from the general spirit of the inventionas set forth in the appended claims.

WhatIclaim is:

1. Abandage comprisin an elastic rous fabric formed of paralle strands ocomparatively heavy weave, having passing I angularly disposed withrespect to the weft threads, and to adjacent warp threads, whereby toprovide an elastic fabric, and an adhesive material formed as a coatingon said strip. 7

3. A bandage comprising a woven, elastic, porous fabric and,a layer ofadhesive material on said fabric, said fabricbeing extensible in onedirection without appreciable contraction in the other, .whereby uponthe application of said bandage in stretched condition to a member theadhesive material stretchesand cracks whereby a porous covering isobtained.

age is under tension as is the case in actual use, the warp members 8are considerably apart from one another and with respect to the woofmember so that the elastic and porous qualities of the same are readilyap- It will be noted that the fabric illustrated is one which willstretch in one direction without appreciably contracting in the other,so that the fabric is rendered more porous on stretching. As a result,the adhesive coating. on the fabric is broken up into separated bands orsections, the spaces between the latter making the whole mass of bandageporous when the bandage is stretched about a limb.
